What it does

Archive old emails locally and free up space without losing anything. Shutting down a hosting plan or switching providers? Save everything before it's gone. Works with Gmail, Outlook, Yahoo, and any IMAP provider. OAuth2 login, threaded conversations, full search, attachments included. Your emails, your hardware.

  An open-source email archiver with full-text search capabilities2025 · openarchiver.com · ▲9

  Hey HN, I’d like to share an open-source project I’ve created. It is an email archiving tool that can back up your whole email system with full-text search capabilities. The project is called Open Archiver, and it is able to archive and index emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and any IMAP-enabled email inbox. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage). Some features: - Archive and index all emails and…

  mailtrim – find what's actually filling your Gmail inboxApr 2026 · ▲34

  I always assumed Gmail bloat came from large attachments. Turns out 3 senders were responsible for 30% of my inbox — thousands of tiny emails I'd never thought to clean up. I built mailtrim to surface this pattern: - ranks senders by actual storage impact (not just count) - confidence scoring on what's safe to bulk-delete - 30-day undo on everything — nothing is permanent by default - runs entirely locally, no email data leaves your machine Free, open source (MIT). No subscription, no backend. One friction point upfront: Gmail API setup is one-time, ~15 min. After that it's just `mailtrim…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok&#x2F;s prefill and 1200 tok&#x2F;s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
